DISH-WASHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 793,395, dated June 2'7, 1905.

Application filed November 19, 1904. Serial No. 233,545-

] all whmn it may concern:

Be it known that we, ZOUAVE S. RANDLE- MAN and CHARLES L. RANDLEMAN, citizens of the United States, residing at Des Moines, in the county of Polk and State of Iowa, have invented a new and useful Dish-l/Vashing Machine, of which the following is a specifica tion.

Our object is to avoid the drudgery and prevent the waste of time and labor incident to washing dishes by providing an improved machine specially adapted for washing a plurality of dishes at the same time.

Our invention consists in the construction, arrangement, and combination of operative mechanism with a tub, as hereinafter set forth, pointed out in our claims, and illustrated in the accompanying drawings, in which- Figure 1 is a side view of the machine mounted on legs to support it in an elevated position. Fig. 2 is a central transverse sectional view that shows the position of all the operative parts relative to each other and the tub with which they are connected. Fig. 3 is a modification of Fig. 2 and shows a wooden tub provided with an auxiliary and removable bottom adapted to retain dishes at its circumference. Fig. 4 is a top view. and Fig. 5 a side view, of a skeleton adapted to retain dishes at the circumference of the tub and also adapted for lifting and carrying dishes. Fig. 6 is a small top view that shows the shapes of the three covers on top of the tub.

The numeral 10 designates a tub preferably made of galvanized sheet-iron. It may vary in size as desired. A frame consisting of a wooden bar 12, fixed to the top of the tub, as shown, or in any suitable way, and a metal post 13, lixed to its end and to the bottom of the tub, serve as'a support for the operative devices mounted on the frame. By not extending the bar 12 from one side of the tub to its other side and supporting its inner end by a post 13 provision is made for lifting semicircular trays in and out of the tub. A shaftbearer 14 is fixed on the outer end of the bar 12 and another shaft-bearer 15 on the inner end thereof. A rotatable shaft 16 is mounted in said bearers and a bevel gear-wheel 17 fixed to its inner end and a crank-handle 18,

detachably connected with its outer end. A rotatable shaft 19 is extended up through a bore in the bar 12 and. a bearing in the shaft-bearer 15 and a bevel-gear 20 fixed to its top to suspend the shaft. The lower end of the suspended shaft 19 has a flange 21 at its bottom, and to it is fixed a broad water-beater 22, preferably made of wood, as shown, or in any suitableway in such a manner that it will be suspended to be rotated intermittently in reverse ways as required to throw water in the tub against dishes retained within and at the circumference of the tub. A bearer 23, integral with the bearer 15, supports a pin 24, that enters a bore in the top of the shaft 16 and aids in keeping said shaft perpendicular when it is rotated as required to actuate the broad flat water-beater 22, that is fixed to the shaft and suspended therefrom to rotate therewith. Covers 25 are hinged to the sides of the bar 12, and a cover 26 is hinged to the top of the tub.

Semicircular skeleton trays 27, made of wire, as shown, or inany suitable way, when placed in the tub are adapted for placing dishes therein to be retained at the circumference of the bottom portion of the tub. The upright wires 28 at the outer arcs of the trays are preferably longer than those at their inner concentric arcs, and the trays are narrow enough to allow the water-beater 22 to rotate between them as required to throw water violently against dishes in the trays by centrifugal force in such a manner as to speedily wash the dishes.

It is obvious soap and hot water can be used in a common way to aid in cleaning the dishes and that the water may be kept hot by placing the tub on the stove or placing a heater under the tub. By reversing the motion of the water-beater it is evident the water may be forced against both sides of plates and other dishes set up crosswise in the trays.

Fig. 3 shows an auxiliary removable bottom in a small wooden tub adapted for family use and wooden pins 29 fixed thereto to serve as a means for retaining dishes at the circumference of the tub as required to allow the water-beater 22 to be rotated in the tub, and a bar 30 is fixed across the top of the tub to support the suspended water-beater and its operative mechanism, as shown, or in any suitable way. 7

Having thus set forth the purpose of our invention and the construction, function, and arrangement and combination of all its parts, the practical operation and utility thereof will be readily understood by persons familiar with the'art to which it pertains.

What we claim as new, and desire to secure by Letters Patent, is

1. In adish-washing machine, atub, a bar to support gearing fixed to the top of the tub at its outer end and extending part way across the tub, a post fixed to the bottom of the tub and to the inner end of said bar to suspend a rotatable water-beater in the tub. means for agitating the water and means for holding the dishes for the purposes stated.

2. In adish-washingmachine, atub, aframe consisting of a horizontal bar fixed to the tub at its outer end and extending part way across the tub, a post fixed to the inner end of the bar and to the bottom of the tub, a rotatable shaftin bearings fixed on the top of said frame, a bevel gear-wheel fixed to the inner end of said shaft, avertical rotatable shaft suspended in bearings on the top of said frame and in the center of the tub, a bevel gear-Wheel fixed to the top of said shaft and a fiat water-heater fixed to its bottom, and means for retaining the dishes to operate in the manner set forth for the purposes stated.

3. Inadish-washing machine, a tub, a frame to support gearing, consisting of a bar extending part way across the tub, and a post at the inner end of the bar fixed to the tub, bearers fixed on top of the frame for a horizontal shaft, a rotatable shaft in said bearers, a bevel gear-wheel on the inner end of said shaft, a rotatable vertical shaft suspended from the frame in the center of the tub and provided with a bore in its top and a bevel gear-wheel fixed to the top of said shaft, a bearer for supporting a pin fixed on top of the frame and a pin in said bearer and said bore in the top of the suspended shaft, and

means for retaining dishes to operate in the 15 manner set forth for the purposes stated.

4. In adish-washing machine, atub, aframe consisting of a horizontal bar extending part way across the tub and a post fixed to the bottom of the tub, bearers fixed on top of the frame, a horizontal shaft in said bearers, a bevel gear-wheel fixed to the inner end of the shaft,a rotatable vertical shaft suspended from the inner end portion of said frame and central relative to the tub, abevel gear-wheel fixed to the top of said shaft and a flat waterheater fixed to the bottom of said shaft and means for retaining dishes at the circumference of the lower portion of the tub, to operate in the manner set forth, for the purposes stated.

5. A dish washing machine comprising a tub, aframe consisting of a horizontal bar extending part way across the tub and a post to support gearing fixed in the tub, a rotatable shaft in a horizontal position mounted on top of the frame, a rotatable shaft in a vertical position suspended from the frame and the two shafts connected by bevel gear-wheels, a flat water-beater fixed to the vertical shaft and suspended in the center of the tub and semicircular trays for retaining and carrying dishes, arranged and combined to operate in the manner set forth, for the purposes stated.

6. A dish -washing machinecomprising a tub, a horizontal bar and means to fix it to the tub, bearers fixed on top of the frame, a horizontal shaft in said bearers, a bevel gearwheel fixed to the inner end of the shaft, a rotatable vertical shaft, suspended from the inner end portion of said frame and central relative to the tub, a bevel gear-wheel fixed to the top of said shaft and a flat water-beater fixed to the bottom of said shaft and means for retaining dishes at the circumference of the lower portion of the tub, to operate in the manner set forth.
